The T1119RF allows you to add a wireless thermostat to your existing Venstar model T1800 or T1900 thermostat. NOTE: This product will only work with the T1800 and T1900 thermostats, which are sold separately.

This accessory will allow you to control your T1800 or T1900 thermostat from any location in your home using the handheld T1100RF Wireless thermostat.

Operation is simple! When a button is pressed on the T1100RF it will take complete control of the thermostat. From the T1100RF you can change the mode of your thermostat, turn the fan on, and even engergize your heating and cooling system. To transfer control back to the T1800 or T1900 thermostat, press any button on that thermostats keypad (except for the outside button).

FEATURES:

Transmits through walls and floors - range up to 500 feet in clear air

This product meets my need of a wireless portable thermostat for an upstairs room, but it lacks refinement.

My main areas of complainant are:

1) Confusing controls, this unit could really use a couple more buttons to make setting the unit more intuitive.

2) No obvious indicator that the wireless unit has control of the HVAC system.

3) Lack of wireless strength indicator, while the 415 MHz communication frequency probably does a good job of reaching most parts of a standard size house, I think it is unforgivable that there is no way to see the connection strength.
